deliver treatment or tumor involving both hemispheres or with subependymal/cerebral
spinal fluid (CSF) dissemination

6. Tumor position that could, in the Investigator's opinion, pose the risk of
penetration of the cerebral ventricular system during inoculation with the study drug
(Note: If penetration of the ventricular system is suspected or confirmed, G207
administration must be aborted.)

7. Tumor locations that would expose the patient to unacceptable risk with radiation
therapy
